I have been getting a raised welt at the site that takes two or three days to settle, and it started long after I had supposedly got the technique right.
The three that fix most of it: room temperature, let the alcohol dry fully, and rotate quadrants rather than points.
The narrow version of the question is whether site reactions are a material issue or a technique issue, and what people changed that actually helped.
I would rather have one careful answer than five confident ones.

Has anyone on injection-site reactions tried splitting their dose across two injection sites? My provider mentioned some patients do this at higher doses (2.4mg sema or 15mg tirz) to reduce injection site reactions.
I'm about to move to 2.4mg and want to minimize the lump that forms at the injection site.

Nurse here. I see both sides of injection-site reactions in my clinical practice.
I manage about 112 patients on GLP-1 agonists at our weight management clinic. The most common issue I see related to injection-site reactions is patients not being adequately informed about what to expect. Setting realistic expectations up front is everything.
Practical tips from the clinic floor:
• Rotate injection sites religiously — use a log
• Let the alcohol dry COMPLETELY before injecting
• Don't massage the injection site
• Keep medication refrigerated until use, then room temp is fine for up to 28 days

Can confirm. Same sequence, different timescale.
Adding the clinical framing, because it changes how the question reads.
Injection site reactions and injection-site reactions: I was getting red, itchy welts at every injection site that lasted 3-4 days. Turned out I was allergic to the alcohol swab, not the medication!
Switched to chlorhexidine prep pads and the reaction stopped completely. If you're having persistent injection site reactions, consider this possibility before blaming the drug.
